Can't save or export after welding

[dako64]

After welding to remove a hole, an internal error will prevent me from saving or exporting a model. It also deletes the wings file I am working on leaving me only with an autosave (wings~) file. Repeated the process a few times to make sure it was the welding. I was able to delete the hole without the tool, but could still could not save.

If you made use of the .Hole. command to create those holes there is a proper command to remove them - select any face that surround the hole and select the command .Hole. with [RMB] option.

99% of the times we see this log starting with reference to do_renumber is because there is inconsistencies in the mesh - usually caused for "improper" operations. In this case, you probably can fix it by using the command Cleanup in the body [b] mode - after select the object.
